FIND FILES ATTACHED -MISTER, MIST, SIDI-

(español abajo)

I'm sorry for being one week late. This was meant to be a special release for the 4th of July but last week was very busy and couldn't finish it. So here it is anyway, happy 4th of July (!)

This is Konami doing another sports game. And it's a really fun one. I originally only met it in the Amstrad CPC. It was a very well done port, fast, good music, impressive graphics... So when I was able to grab the ROMs, I made an emulator for it. That was my last emulator work. I mentored Manuel Abadia while doing it. He then became a great contributor to MAME and we owe him the work of hacking the encrypted Konami CPU.

This game uses a new ADPCM chip, the NEC uDP7759. I had to make a core for it. It is now available for all developers here.

This is the second title in the Konami 007121 series. It is clear now that the knowledge of this chip is not good enough. Emulation is done at the moment via ad-hoc hacks for each game. And not even the hacks work ok. So we need a proper reverse engineering work on it. Pastblaster has offered a donor board for the chip (thanks!). I have asked Furrtek to take it. He's done some work on Konami before and he is really good at analyzing gate arrays like this one.

Please, remember that Konami 007121 games (Contra and Combat School) are still in beta phase. Please do not distribute.

And from today, I am officially working on Q-Sound.

Esto estaba previsto para el sábado pasado. Pero el hombre propone y Dios dispone. Dificultades como el nuevo chip de ADPCM que incorpora el juego me retrasaron. Por cierto, este chip ya lo he publicado para todos aquí.

Yo nunca conocí esta maquina. Como con Gryzor, yo sólo vi la versión de Amstrad CPC pero era buenísima. Buen ritmo, buena música, ¡y jugable que no siempre pasaba! Así que cuando por fin conseguí las ROMs me puse a hacer el emulador. Ese sería mi último emulador. En esa época hice de mentor para Manuel Abadía. Después de aprender el oficio, Manuel se convirtió en un prolífico autor dentro de MAME. Le debemos mucho, incluida la desencriptación de la CPU de Konami.

Ha quedado claro ya con este juego que lo que se sabe del chip Konami 007121 no es bastante para hacer un buen trabajo. Los emuladores hacen chapuzas para cada juego y aun asi no los sacan bien. Gracias a Pastblaster, vamos a donar una placa con dos de estos chips a Furrtek para que extraiga el circuito. Bueno, si acepta el trabajo.

Por favor, estos juegos de Konami están aun en fase beta. No los paséis.

Ah, y a partir de hoy estoy haciendo oficialmente el Q-Sound.

Thanks alot for your hard work. I already have the pcb for this. Now I can sell it!😀

Skutis

Of the game in demo mode. If you specify more exactly what sequences or times. I can do that. I believe it is an original. But not sure. Have to check when I get back home. I’m on a holiday right now.

Combat School el revienta joysticks, entre ellos el mío de Amstrad :D Yo sí que lo conocí en recreativa y era una buena máquina para picarse con los colegas. Gracias por este core.

Jessica Marshall

Yes, shout out for the CPC version! That was my first encounter as well, my brothers and cousins took turns with the joystick and worked as a team. We could never beat Firing Range 3.

ALFREDO CANAS

wow, never heard about this game before it's like Track and Field 2 but for the Military jeje.

Andi

I never had it but adverts for the microcomputer ports were all over magazines back in the day, the logo is very familiar to me :)

John Stringer

I love your Amstrad CPC memories as I also share them. Maybe Chase HQ or Wec Le Mans one day? ;)

Craig Somerfield

If I remember correctly this had a trackball controller ... well the one I remember did 😁

David Filskov

Super!! - btw - should the MRA point to 'combasc'? - right now it points to 'combatsc' (t added)

Oscar Laguna Garcia

Juegazo machaca botones!! Me encanta, lo jugue mucho en recreativa de peque. ¿Tiene db15 para que así funcione con mi recreativa de casa? Gracias!

Xzarian

Sweet! Looking forward to Q-Sound too!

Joe Drilling

Very cool, what an offbeat title! Also, STOKED for CPS Dash!

RoC

Such a good surprise Jotego: super thanks !

Danilo Dellafrana

looks amazing, one of my fave sport games. I almost finished it (even after all these years the White House mission is still a pixel perfect pain) and I have noticed 2 glitches, In shooting range 2 the top of the screen where the score is looks scrambled as well as the strenght bar for the 2p in arm wrestling . Hope my report can help you in your work on the beta, these Konami 007121 games are amazing.

James Kilgore

Not working for me. Getting a bad rom 2 error at startup

DrMnike

Where should I put the folder with the core and the gane? Do I need the mame file as well? Can somebody help how to install the game please?

Milspex

This never went public or did it? I have it obviously but I was wondering
